This publication examines the ethical issues linked to the use of assistive technology for/by people with dementia. A brief overview is provided of the three main issues of importance, namely dementia, assistive technology and ethics. This is followed by a discussion of the various ethical issues linked to the use of AT (based on an extensive review of literature) which addresses not only possible disadvantages but also looks at the positive implications of the use of AT and how it can contribute towards respecting certain ethical principles with regard to people with dementia. Alzheimer Europe presents its position and guidelines on the ethical use of AT for/by people with dementia and proposes an ethical framework for decision making. This publication is targeted at a wide audience including people with dementia, carers, health and social care professionals, service providers, AT designers, researchers and policy makers.
